LyX: Missing title when passing `ignorenonframetext` to Beamer

Passing ignorenonframetext as an option to Beamer, causes it to ignore all the text that is not inside a frame. It is useful when you want to add content for the article version of the presentation (or simply script lines for yourself) that would not show in the regular presentation. LyX puts the title elements outside any frame. Therefore, if you use ignorenonframetext you end up missing the title frame. The solution is to manually wrap the title block (the title, author, institute, etc.) in a frame and append to it \maketitle. This will cause the title frame to be rendered correctly.

\lyxframeend Undefined when Using Beamer with Lyx

I’m using LyX for the first time with Beamer. Making the title page was smooth. But when I’ve tried adding a new frame (using BeginFrame) I was confronted with the following error

 \lyxframeend
                 {}\lyxframe{Outline}
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

After comparing my document to example (working) beamer documents I’ve found out that you must have an EndFrame command after your last frame. Too bad it wasn’t documented anywhere I’ve found as this little thing drove me crazy.
